EXPLOSIVE COMPOUND.

No Drawing.

To all whom it may concern:

Be it known that 1, WILLIAM FLEMING HANCOCK, a subject of the King ofGreat Britain, and resident ,of Haliburton, in the county of Haliburton,in the Province of Ontario, Dominionof Canada, have invented a certainnew and I do hereby declare that the followin is a full, clear, andexact description of t .e same.

The invention relates to a new and useful explosive compound asdescribed in the following specification.

The objects of the invention are, to obviate the dangers anddifficulties met with in the use of dynamite and like explosives usedfor blasting purposes, and to devise a compound which will notbeaii'ected by concussion and will not freeze.

The compound consists essentially of the following ingredients,'in orabout the following proportions, namely :chlorate of potash,-16 parts;nitrate of potash, 12 parts; brown sugar, 3 parts; bichromate of potash,3 parts; sulfur, 6 parts; charcoal, 1 part; lampblack, 1 part. i

The above ingredients are preferably mixed in the following order :Thechlorate and nitrate of potash are thoroughly mixed together and theremaining ingredients are added to the mixture one at a time and eachthoroughly mixed into the compound of the previous constituents beforethe next is and useful Explosive Com Specification of Letters Patent.Patented J une 13, 1911.

added. The addition of the charcoal in a fine ground state acts as anabsorbent to take up any moisture in the other ingredi-' ents, therebykeeping the mixture in a pulverized state.

The above compound will not explode through concussion and containing noliquids will not freeze and for a proportioned amount results in a muchheavier explosion than that from the dynamite charge.

It will be readily understood that as the compound will not freeze, thedanger incident to thawing and contact with fire is' reduced to aminimum and as it willvnot explode through concussion, may be handledwith much greater facility and safety than dynamite. Further, thepresent mixture is much cheaper to produce than dynamite.

' What I claim as my invention is An explosive compound 'consistinchlorate of potash, 16 parts; nitrate o ash, 12 parts; chroinate ofpotash, 3 parts; sulfur, 6 parts; charcoal 1 part and lampblack 1 part.
